To provide a mixing device for improving mixing efficiency in a wider flow rate range with a comparatively simple shape, and a micro flow channel device using the same.SOLUTION: A mixing device mixes a plurality of fluids in a mixing region 8. The mixing region has first and second wall surfaces 21 and 22 that face each other, a first obstacle structure 6 that projects toward the second wall surface from the first wall surface and functions as an obstacle against a flow of a fluid, and a second obstacle structure 7 which projects toward the first wall surface from the second wall surface, and functions as an obstacle against the flow of the fluid. The first obstacle structure is composed of a plurality of first obstacle structure constitution parts 61, ..., 64 that are arranged side by side, and the second obstacle structure is composed of a plurality of second obstacle structure constitution parts 71, ..., 77 that are arranged side by side. The first obstacle structure constitution parts and the second obstacle structure constitution parts are arranged in a mutually asymmetrical state with a center line X of a single flow channel as an axis.SELECTED DRAWING: Figure 3

To provide a flow channel element that can be manufactured with a simple and minimal number of steps. [Solution] The flow channel element comprises a substrate, a film formed on the substrate, and a modified portion of the film that extends linearly along the substrate. A first flow channel is formed between the substrate and the film, which are peeled off on both sides of the modified portion, along the modified portion.
